PGL Command Set Standards

To use the PGL commands, follow a set of standards in constructing the commands you send to your printer.

Special Function Control Character (SFCC)

The SFCC identifies Special Function Commands that are used in NORMAL Mode and Execute Mode. The character you use for the SFCC is based on the host computer interface requirements of your system. The SFCC must be a printable character and it must be placed at the beginning of a new line before the command or data. The default SFCC is ~ (tilde). This character may be changed using the SFCC Change Command or by accessing the Configuration menu through the printer control panel.

Since the SFCC can be changed to any printable character and may be different due to your host computer requirements we will use the ￿symbol to represent the SFCC in all command sequences.

Parameter Delimiter

Each parameter on the command line must be separated from other parameters by a delimiter. The delimiter recognized by your printer is the semicolon (;).

NOTE: Do not place blank spaces between the delimiter and the next parameter. A missing or misplaced delimiter causes an error.

Case

The PGL language requires that all commands be entered in upper-case characters.

Line Terminator

In PGL each command line must be terminated by a Line Feed, Carriage Return with a Line Feed, or a Form Feed command. If you do not terminate the command line properly, the command will not be accepted by your printer. Refer to your system documentation to determine how to perform a terminator function (Line Feed, Carriage Return with Line Feed, or a Form Feed command).
